Measure the quality of an electric heating tube and use a multimeter
Then the high resistance meter between measuring deflection of pile head connection with the heating pipe shell, resistance should be infinite. If there is only several European resistance, electric insulation breakdown, when there will be risk of leakage, the heating pipe is best not to use.
Yes, you can use a multimeter to measure the quality of the heater
Measure the junction of the heating pipe with small resistance. The resistance should be below several hundred ohms. The electric resistance of the big heat pipe will be smaller and the energy will pass, but the resistance value is great. The electric heating tube may also have been burnt.
